Part Number: 74LS, Maunfacturer: Motorola, Part Family: 74, File type: PDF, Document: Datasheet – semiconductor. These 8-bit shift registers feature gated serial inputs and an asynchronous clear. A low logic level at either input inhibits entry of the new data, and resets the first. It has 2N states where ‘N’ is the number of flip-flops. So here is how to make a Johnson counter using IC 74LS Here are some of the features of IC

This 8-bit shift register features gated serial inputs and an. The gated serial inputs A and B permit complete control over incoming data as a low at either or both input s inhibits entry of the new data and resets the first flip flop to the low level at the next clock pulse.
A high level input enables the other input which will then determine the state of the first flip-flop. Data at the serial inputs may be changed while the clock is high or low, but only information meeting the setup requirements will be entered clocking occurs or the low-to-high level transition of the clock input. All inputs are diode- clamped to minimize transmission-line effects.
